The knives are out for table-flipping reality star Teresa Giudice and her meathead husband, Joe.

The crass, lavish-living couple — who’ve made more enemies than friends on Bravo’s “Real Housewives of New Jersey” — appeared in Newark federal court yesterday on tax-, mail- and wire-fraud charges that could land them in jail for 55 years — as their enemies celebrated their misfortune.

“There is a God!” arch nemesis Kim “Kim G” Granatell told The Post. “I’ve been waiting for this for a long time.”

Granatell said Teresa bullied her on the show because she criticized the Giudices for their spending on lavish parties, a $140,000 Maserati, home furnishings and trips despite filing for bankruptcy in 2009.

She once offered to buy all of Teresa’s possessions if her house went into foreclosure so she could resell them on eBay.

“We were on the show together, and Teresa did not want me around because she knew I knew too much,” said Granatell, who appeared on “Real Housewives of New Jersey” for two seasons.

Granatell suspects the feds started following the couple — who’ve been accused of bilking four banks out of nearly $5 million in mortgages using fake tax forms and other bogus paperwork — after Joe’s former business partner, Joe Mastropole, sued him for forging his signature on a mortgage application in 2007.

“She hated me because she knew I knew what she was about,” said Granatell.

“That she was living in a broken-down house and her back yard was on a highway,” Granatell said of the couple’s mansion in Towaco that the couple added on to as their wealth increased.

“We knew what she was doing, she ruined a lot of businesses.”

The scene outside of the New Jersey courthouse was made for reality TV.

Joe’s parents, who co-signed a $500,000 bond to free the couple with four daughters, lashed out at reporters, telling them to “go to hell.” His elderly mother, Filomena, slapped a 1010 WINS reporter’s microphone and shouted obscenities.

When asked if she was worried about her son, she shot back, “None of your f–king business.”

Joe faces being deported to Italy if he is found guilty of just one of the 39 counts in the indictment, prosecutors said — as it emerged yesterday that he is not a US citizen.

Meanwhile, Teresa’s lawyer, Henry Klingeman, said she’s being targeted because of her celebrity status.

He said he was concerned how her belligerent image on the show might influence the jury.
